The agency says officers detained the man and took him to the city’s Protective Care Centre, a detox centre that can hold people for up to 72 hours.

It says that during the handover to staff, the man started to resist and kicked an officer’s leg, prompting police to force the man to the ground.

The agency says officers knocked the man unconscious in their efforts to regain control of him.

It says the man regained consciousness and continued to resist officers while being transported to the hospital, where doctors found the skull fracture.

The watchdog says it’s mandated to investigate because the arrest involved serious injury.
